ABSTRACT:
A method and system for balancing host write operations and cache flushing is disclosed. The method may include steps of determining an available capacity in a cache storage portion of a self-caching storage device, determining a ratio of cache flushing steps to host write commands if the available capacity is below a desired threshold and interleaving cache flushing steps with host write commands to achieve the ratio. The cache flushing steps may be executed by maintaining a storage device busy status after executing a host write command and utilizing this additional time to copy a portion of the data from the cache storage into the main storage. The system may include a cache storage, a main storage and a controller configured to determine and execute a ratio of cache flushing steps to host write commands by executing cache flushing steps while maintaining a busy status after a host write command.
